We Hold Ourselves to a Higher Standard
Most peptide vendors stop at purity percentage. Soha Peptides runs 6 independent verification points on every batch — including endotoxin screening that others skip, sterility checks by an accredited lab, and sequence accuracy confirmation via mass spectrometry.
6-POINT VERIFICATION PROTOCOL
Purity, Sequence Identity, Endotoxin Level, Sterility, Content, and Appearance — every batch, every compound, no exceptions.
ENDOTOXIN SCREENED
Endotoxins trigger immune reactions even when a compound looks visually clean. We test every lot to confirm LPS-free material.
STERILITY VERIFIED
Filtration alone does not confirm no viable microbes exist. Our sterility checks are performed by an ISO 17025 accredited lab.

The 6-Point Quality Standard Others Don't Use
HPLC PURITY ANALYSIS
High-Performance Liquid Chromatography confirms the compound makes up 99% or more of total content. The full separation profile is documented and published.
MASS SPECTROMETRY IDENTITY
Confirms the exact molecular identity and sequence accuracy of each peptide. Protects against mislabeling and ensures you receive precisely what was ordered.
ENDOTOXIN SCREENING
LAL testing detects bacterial endotoxins that cause immune reactions — even when the compound looks visually clean. Most suppliers skip this step entirely.
STERILITY VERIFICATION
Performed by an ISO/IEC 17025:2017 accredited laboratory. Confirms no viable microorganisms are present — going beyond sterile filtration alone.
CONTENT QUANTIFICATION
Verifies the stated weight and concentration is accurate. Every milligram you receive is what the vial claims — no underdosing, no overpromising.
APPEARANCE & PHYSICAL CHECK
Visual inspection and lyophilization quality. Verifies proper freeze-drying, packaging integrity, and that no physical contamination occurred during production.
The standard, measured.
Every batch is evaluated against the same verification requirements.
